Looking for a pre/processor

Hi,

I currently have a two channel front comprised of a Benchmark USB DAC and Bel Canto Pre. These components feed a pair of active Linkwitz speakers. I recently purchased an Oppo bluray player and a Hidef LEd TV. I would like to simplify my front end and get a processor to replace the Benchmark and Bel Canto.
My wish list for the processor is:
Quality DAC to replace the Benchmark
Solid pre for running two channel. I plan on staying strictly two channel for no
HDMI input and output for the Oppo and LED TV
USB input for my mac mini but can have SPDIF or Optical

What are my choices?

Thanks
Neil
